patch 9.0.1080: the "kitty" terminfo entry is not widespread
Problem: The "kitty" terminfo entry is not widespread, resulting in the
kitty terminal not working properly.
Solution: Go back to using "xterm-kitty" and avoid the problems it causes in
another way.

Many other terminals depend on this. However, Kitty is not fully xterm compatible. The author suggested to -ignore the "xterm-" prefix and use the terminfo entry anyway, but that -conflicts with what is needed for other terminals. Therefore Vim removes the -"xterm-" prefix from "xterm-kitty" when it comes from $TERM. +ignore the "xterm-" prefix and use the terminfo entry anyway, so that is what +happens now, the builtin xterm termcap entries are not used.
